- In dealing with a typical case, where the examiner rejected the application as being unpatentable and the reexamination board supported the rejection as well, Ken conducted a careful study and comparison between the technical solution of the subject application and the prior art in the reference documents with respect to the reexamination opinions. A detailed and persuasive argument was made by starting from basic theories such as fluid mechanics with step-by-step illustration and painstaking analysis, to highlight the prominent substantive features and significant technical effects of the patent. Finally, our observations were recognized by the reexamination board, which revoked the refusal decision and allowed the subject application.
